I like to do SITD before doing FMQ just to help keep thing stabilized, so if this was my quilt I would probably SITD around the larger blue squares before doing the FMQ.
The FMQ you have planned should be enough quilting alone, though, so it's really up to you! What do YOU prefer?
Beautiful batiks, by the way. I love those colors. It's going to be a lovely quilt when you're done, whichever quilting method you choose.
